I was able to reproduce it to older Samba server (4.12.5) and could
workaround the Samba server bug by using mount option "compress" on
the client (which won't do anything different since it is not
supported but interestingly it avoids the problem by adding another
context at the end).
The general problem might be solved by just moving the now optional hostname
context in fs/cifs/smb2pdu.c back between build_encrypt_ctxt and build_posix_ctxt.
I encounter the issue with a Synology Diskstation, and there might be
much more people running into the problem when this kernel becomes more
common...

I lean toward thinking that this is a Samba bug (although I don't see
it on my local system - it works to samba for me, although I was
trying against a slightly different version, Samba 4.15.5-Ubuntu).
Looking at the traces in more detail they look the same (failing vs.
working) other than the order of the negotiate context, which fails
with POSIX as the 3rd context, and netname as the 4th, but works with
the order reversed (although same contexts, and same overall length)
ie with POSIX context as the fourth one and netname context as the
third one.
The failing server code in Samba is in
smbd_smb2_request_process_negprot but I don't see changes to it
recently around this error.
Does this fail to anyone else's Samba version?
This is probably a Samba server bug but ... seems odd since it doesn't
fail to Samba for me.
Jeremy/Metze,
Does this look familiar?
Maybe this one:
https://git.samba.org/?p=samba.git;a=commitdiff;h=147dd9d58a429695a3b6c6e45c8b0eaafc67908a
that went only into 4.15 and higher.

Nice catch, I can confirm that adding this patch to debian samba
2:4.13.13+dfsg-1~deb11u3 package makes the mounts work again. How do we
get this patch into debian?
Best regards,
Julian
I have now filed a bug against debian samba package:
